Life is too short to spend time deconstructing specious arguments that rely on easily caricatured straw-men. Instead, I will quote Thelonious Monk.
Where's jazz going? I don't know. Maybe it’s going to hell. You can't make anything go anywhere. It just happens.Update: I am also reminded of what Delmond Lambreaux of Treme (a jazz trumpeter based loosely on Christian Scott according to Patrick Jarenwattananon) said in episode 4 earlier this year: "Jazz hasn't run hot or cold since bebop. It just is, man."
